[GAMEPLAY] Screen changes with button presses and pings with just clicks

I've been having this weird bug that happens completely randomly. When my game starts, my clicks turn into pings (I set them to ping only if i hold g) without holding g, my screen changes from windowed to full screen when I press a key and some esc and p key don't do what they're assigned to do. I looked everywhere and couldn't quite find a permanent solution to the problem. I'm curious to see if anyone else has experienced anything like this or if Riot even knows this even exist.
